As we all know, the polyester fiber net is made from a single polyester filament, and part of our polyester filament is made by us. A good polyester mesh needs better polyester filaments to support it. so I'm going to talk about the production process of Hebei Defeng polyester filament.

   Initially, polyester slices are dried by hot air and then squeezed out of the extruder into a single wire shape, and then the single wire is pulled into a process standard through four extension machines. During this period, the required single wire needs to be reached through hot bellows and stereotypes. High temperature and high strength process standards, And in the winding machine to carry on the regulation, and then sent to the inspection department for all aspects of testing, and finally for packaging. This is our Hebei defeng polyester single wire production process.

Our polyester single wire has the following unique and high quality properties after multi-process processing:

1. Have acid resistance, alkali resistance, wear resistance, high temperature resistance, service life is several times that of other materials.

2. The net surface of the polyester network is flat, tensile strength, good breathability and high heat transfer efficiency, which can save energy and save cost for users.
